Urgent need for automobile air conditioning testing.

1. In the condenser, the refrigerant changes from gas to liquid.

2. The high pressure in the high pressure part of the air conditioning system may be due to too much refrigerant or air in the system.

3. When the air conditioning system is changed from R- 12 to R- 134a, the original liquid storage dryer should be replaced with a dryer containing __XH5__ desiccant.

4. If the distance between the armature and the turntable is too close, the electromagnetic clutch of the air-conditioning compressor will not be completely separated when the clutch is disconnected. If the distance is too far, it is easy to slip when clutch.
